The thyroid gland produces thyroxine and triiodothyronine which essential element is iodine. It order for these hormones to function they need iodine. Without these hormones the thyroid can not function properly and swells (goiter). Reduced function in the thyroid also caused the hypothalamus and pituitary gland to produce thyroid stimulating hormone which irritates the thyroid more.

∙ 11y agoIodine is necessary for making thyroid hormone. If it is deficient you will not make the hormone and in response the thyroid gland will swell causing a lump in the front of the neck known as a goiter.
Symptoms of low thyroid include weight gain, fluid retention, cold intolerance, fatigue, muscle weakness, constipation and others.

∙ 9y agoThe body does not make iodine on it's own, and you must consume iodine. An iodine deficiency can cause problems with the thyroid including goiter, which is an enlargement of the thyroid gland.

∙ 11y agoIodine is used to produce the hormones thyroxin and tri-iodothyroxin in the thyroid. With iodine deficiency the body can no longer produce these hormones. These hormones are controlled by negative feedback, meaning that these hormones decrease their own production in the thryoid. So without thyroxin and tri-iodothyroxin there is no longer a signal to stop production by the thyroid and therefore the thyroid goes into overdrive while the body loses its thyroid hormones. This results in a goiter(enlargment of thyroid) and HYPOthyroidism(look up symptoms on wikipedia). Iodine deficiency is extremely rare in all developed nations because we add iodine to salt.

What causes goitre?
goitre is less of iodine percent in our body
How does deficiency of iron and iodine affect your body?
Deficiency of iron will lead to anemia while lack of iodine leads to thyroid problems.
How does deficiency of iron and iodine effect your body?
Lack of Iodine causes Goitre which is swelling of the Thyroid gland.
How can you make sure that you have iodine in your body?
Our body has thyroid gland behind the trachea.For its proper functioning it requires Iodine.If there is lack of Iodine,it clearly affects on functioning of thyroid gland.Many changes can be seen in body such as Simple goitre(swelling of thyroid),hypothyroidism, hyperthyroidism..etc.By this we can see that Iodine is present in our body.
How does iodine deficiency affect the body?
Iodine is the main building block needed to make thyroid hormone. Thyroid hormone is needed to control your metabolism. If you lack Iodine in your diet, over time, you will develop goiter (enlarged) thyroid gland. This is rare in the US since many salt has iodine in it.
How does goitre affect the body?
it affects your metabolism and can give you mental problems as well as physical problems
What disease is caused by inadequate intake of iodine?
Iodine is used to produce the hormones thyroxin and tri-iodothyroxin in the thyroid. With iodine deficiency the body can no longer produce these hormones. These hormones are controlled by negative feedback, meaning that these hormones decrease their own production in the thryoid. So without thyroxin and tri-iodothyroxin there is no longer a signal to stop production by the thyroid and therefore the thyroid goes into overdrive while the body loses its thyroid hormones. This results in a goiter(enlargment of thyroid) and HYPOthyroidism(look up symptoms on wikipedia). Iodine deficiency is extremely rare in all developed nations because we add iodine to salt. Hope that helps.
What are the nutritional benefits of iodine?
Iodine is very useful for our body. Iodine deficiency can cause thyroid. So just check your iodine level in your salt which you are using in your food. Better use Iodine Salt.
Is Iodised salt harmful to body?
No Iodised salt is produced so that there is a source of iodine to the body, in places like Australia and New Zealand where there is a lack of iodine in the natural surroundings where they would otherwise be taken up with fruit and vegetables.Iodised salt (also spelled iodized salt) is table salt mixed with a minute amount of various iodine-containing salts. The ingestion of iodide prevents iodine deficiency. Worldwide, iodine deficiency affects about two billion people and is the leading preventable cause of mental retardation.[1] It also causes thyroid gland problems, including endemic goitre. In many countries, iodine deficiency is a major public health problem that can be cheaply addressed by iodisation of salt.Iodine is a micronutrient that is naturally present in the food supply in many regions. However, where natural levels of iodine in the soil are low and the iodine is not taken up by vegetables, iodine added to salt provides the small but essential amount needed by humans.(source wikipedia)
How does pyruvate kinase deficiency affect the body?
PKD is caused by a deficiency in the enzyme, pyruvate kinase.
Why Euthyroid patients with goitres are treated with thyroxine?
It depends on the specific type of goiter. Thyroid physiology and pathophysiology is very complex but I will try to be very basic. Iodine deficiency & low production of thyroxine are the main causes for goitres in euthyroid individuals. In mountainous areas dietary iodine deficiency still exists, in some areas as 'endemic goitre' where goitre, occasionally massive, is common. The patients may be euthyroid or hypothyroid depending on the severity of iodine deficiency. Because iodine is essential for the thyroid hormone production. The mechanism is thought to be borderline hypothyroidism leading to TSH stimulation and thyroid enlargement in the face of continuing iodine deficiency. TSH (Thyroid Stimulating Hormone) is secreted from the anterior pituitary gland and travels to the thyroid gland, "stimulating" the gland. Among the multiple effects it has on the gland, TSH causes cells of the gland to increase size and number. This can contribute to a goiter. Thyroxine is a thyroid hormone. It is secreted from the thyroid gland and travels throughout the body affecting many organs. It also travels back to the pituitary gland and causes the pituitary to decrease secretion of TSH since the body has plenty of thyroid hormone flowing. By decreasing TSH, thyroxine also helps to decrease growth of the thyroid gland. Normal Serum thyroxine 51.4-154.4 nmol/L. In certain occasions patients are with low levels of thyroxine ,even though they are within normal range; euthyroids. Therefore TSH secretion is not inhibited, resulting the goitre due to the continuous stimulation of the gland.
If a woman has a severe iodine deficiency during pregnancy her child may have?
Iodine deficiency is especially important in women who are pregnant or nursing their infants. Severe iodine deficiency in the mother has been associated with miscarriages, stillbirth, preterm delivery, and congenital abnormalities in their babies. Children of mothers with severe iodine deficiency during pregnancy can have mental retardation and problems with growth, hearing, and speech. In the most severe form, an under active thyroid can result in cretinism (a syndrome characterized by permanent brain damage, mental retardation, deaf mutism, spasticity, and short stature), though this is not seen in the United States. Congenital hypothyroidism due to iodine deficiency is the most common preventable cause of mental retardation in the world. Even mild iodine deficiency during pregnancy, which may be present in some women in the United States, may be associated with low intelligence in children. 1 SYMPTOMS Page 1 of 3 1 What is iodine deficiency? Iodine is an element that is needed for the production of thyroid hormone. The body does not make iodine, so it is an essential part of your diet. Iodine is found in various foods (see Table 1). If you do not have enough iodine in your body, you cannot make enough thyroid hormone. Thus, iodine deficiency can lead to enlargement of the thyroid (goiter - see Goiter brochure), hypothyroidism (see Hypothyroidism brochure) and to mental retardation in infants and children whose mothers were iodine deficient during pregnancy. Before the 1920s, iodine deficiency was common in the Great Lakes, Appalachian, and Northwestern U.S. regions and in most of Canada. Treatment of iodine deficiency by the introduction of iodized salt has virtually eliminated the "goiter belt" in these areas. However, many other parts of the world do not have enough iodine available through their diet and iodine deficiency continues to be an important public health problem globally. Approximately 40% of the world's population remains at risk for iodine deficiency.
